of "Mattiaci". In the late 1st century AD, Valerius Martialis mentions a kind of soap that was named for the Mattiaci and may have been a local product: Sapo: Si mutare paras longaevos cana capillos, Accipe Mattiacas - quo tibi calva? - pilas. Soap: If you want to change your highly aged hair, use Pilae Mattiacae - why have a bald head? A Cohors II Mattiacorum Milliaria Equitata has been attested by several finds in the Roman province of Moesia inferior (e.g. at Sostra). It may have originated in Mattiaci recruited after the Revolt of the Batavi. The Notitia Dignitatum, an early 5th century document, lists two auxilia palatina, the Mattiaci seniores and the Mattiaci iuniores. The references imply Mattiaci in Roman service. Fictional references Two main characters of the novel series Romanike are Romanized Mattiaci. See also Chatti Batavians List of Germanic peoples References Early Germanic peoples Auxilia palatina
